The medical gas turbine, also known as the dental gas turbine, is an advanced dental medical instrument.

As the old saying goes, toothache is not a disease, it hurts really badly, so dentistry is a very heavy medical classification in all countries, and often a variety of dental treatments need to grind the shell of tooth enamel and dentin to expose the pulp or necrotic tissue from the lesion, so as to facilitate its removal or drug treatment.

However, teeth are the hardest part of the human body, and traditional means cannot achieve the purpose of drilling and grinding teeth, so medical devices specially used for tooth grinding came into being.

In the early days, it was purely mechanical, and the doctor used the pedal to treat the patient with a moving head at the same time, because the speed was only a pitiful more than 1,000 revolutions, not to mention the slow efficiency, and the patient was extremely painful in the treatment process.

Later, with the advent of motors, the traditional mechanical drill bit was replaced by a micro electric drill bit, and the speed was increased by tens of thousands of revolutions from the original thousands of revolutions.

However, due to the inherent shortcomings of the electric motor, the lubrication and water spray cooling device cannot be carried over to the drill bit, and the dentist is often scrambling for treatment.

In the late fifties, Western countries developed a new type of tooth drilling and grinding equipment, that is, the gas turbine, the principle is very simple, that is, the use of compressed air, drive a miniature turbine to rotate, so as to obtain a high speed of more than 300,000 revolutions per minute.

At the same time, because of its purely mechanical mechanism, it is easy to integrate a water spray cooling device inside, so that the patient's mouth can be cooled and cleaned with water while drilling and grinding the teeth, thus reducing the patient's pain.

The principle is very simple, but it is very difficult to make it, and the rest is easy to do, but the difficulty lies in the miniature turbine called the movement.

Not only is it small and exquisite, but the weight is strictly limited to a certain range, which is just that, the key is that the centrifugal force generated by hundreds of thousands of revolutions per minute is quite terrifying, and ordinary materials have not yet reached the index, and they may be torn apart by strong centrifugal force.

In addition, the processing accuracy, the overall airtightness and the special testing equipment all have high requirements, resulting in ordinary enterprises even if they want to do it, but they can't do it.

Because of this, once the gas turbine came out, it was monopolized by a few small companies in the West, not to mention the blank in China, and the vast majority of medical device factories have never even heard of it.

It's just that this kind of high-performance turbine movement is a barrier to the past for domestic medical device factories, and it is very difficult even for some ordinary precision manufacturing plants, but it is not a problem for Tengfei factories.

No matter how complex this turbine is, is it complicated by the turbine in a jet engine?

Not only do you have to endure high temperatures, but you also have to endure high pressure, as for centrifugal force, each square centimeter has to withstand nearly five tons of tearing, the turbine in the gas turbine is just ordinary compressed air, and the working environment is simply not too good.

As for the materials, parameters, and transmission, they are more than one level lower than the aero engine, otherwise the aero engine would not be called the crown jewel of industry.

In order to save money in the past two years, Master Ju and others have been using clock processing equipment to do some miniature testing machines with a diameter of 10 to 20 centimeters to do theoretical feasibility studies, so that the factory has the processing capacity of micro components.

Everything is available, just one product is needed to integrate it into cash, Zhuang Jianye, who was tortured by toothache in his last life, will do high-end, medical equipment is not only high-end, but also thief TM profiteering.

The key is that the entry threshold is high, once the word-of-mouth effect is formed, it is easy to form a monopoly, counting the money to the hand cramps, not to mention, the enterprise is not obvious, very in line with the corporate philosophy of Tengfei factory to make a fortune in a low-key manner.

As for the so-called bladeless fan, TM is a pit, and it may make a small fortune at the beginning, but the problem is the poor intellectual property environment in China, and this thing will have to be made everywhere in less than two years.

At that time, the best outcome for Tengfei Factory is to share the market with a few giants, and if something goes wrong, it may become like that poor VCD invention factory, and it will be hastily closed.

Jet power office is a long-term job, making quick money can only solve temporary needs, but compared to the entire research and development of jet power, it is better to find a long-term, stable and profitable livelihood.

The gas turbine is very good, enterprises like the 517 factory want to do it but can't do it, the large aviation power plants in this system have the technology but can't look down on such pediatrics, such a huge market is so empty, Zhuang Jianye is sorry for his conscience if he doesn't pick it up.

Therefore, Zhuang Jianye is very generous to make all the bladeless fans public, which is a gimmick, attracting people's attention and paying enough attention, its mission is completed, and the remaining gas turbine is the real mainstay.

Because he believes that at this exhibition jointly organized by several ministries and commissions, the leaders of the health system, like the heads of other systems, will inevitably participate, even if there is no medical equipment they want to participate in the exhibition, but for the sake of the call of the superiors to support the development of the arduous national defense and military industrial enterprises, how can the health system also pay some out of their pockets to buy some televisions, refrigerators, electric fans, quilt covers, bed sheets, etc.

What if there was suddenly a medical system in the midst of all these inconsistencies of light industrial products, and the medical system needed to import a large number of medical devices every year?

Obviously, the effect is surprisingly good.

I saw that the old man who exclaimed in surprise put the gas turbine in his hand and looked left, and then looked at it, this is not enough, and asked Zhuang Jianye and Master Ju to connect the equipment and try it, and then a smile finally appeared on his serious face: "En...... From the point of view of feel, it is not worse than foreign products. ”

At this time, Zhuang Jianye had already learned the identity of the old man from the cadres of the ministries and commissions of the aviation system, and sure enough, he was the leader of the health system, his name was Hong Xiaosong, who was transferred from the Union Hospital in Beijing to the health department as the leader last year.

Not only is he a square person, but his medical skills are even more exquisite, especially in otolaryngology, and he is one of the few experts in China, so this Hong Xiaosong is no stranger to dentistry, and even more proficient than ordinary experts.

After learning the situation, Zhuang Jianye immediately explained to Master Ju, and soon Master Ju got two hard-boiled eggs, Zhuang Jianye hurriedly took it in his hand, walked to Hong Xiaosong, who was taking the gas turbine to inspect carefully, and said with a smile: "Doctor Hong, I heard that foreign skilled doctors can engrave words on eggs, and you are also an expert in this area, can you also mention one for us on the eggs." ”

As he spoke, he handed over two boiled eggs as if offering a treasure.

Originally, Hong Xiaosong was very happy to see domestic medical equipment here, and he was reluctant to put it down when he got it in his hand, but now when he heard this, he scratched his itch, and nodded without thinking about it: "Okay!"
